Rabbit Polyclonal Antibody

Specifications

Product Data
Applications	ELISA, WB
Recommend Dilution	WB: 1:500-1:1000 ELISA: 1:1000-1:2000
Reactivity	Escherichia coli
Host	Rabbit
Clonality	Polyclonal
Immunogen	Anti-HMW E.Coli Host Cell Proteins Antibody was prepared by repeated immunizations with a mixture high molecular weight (HMW) proteins from E.Coli (BL21).
Specificity	HMW Host Cell Protein A purified antibody is directed against high molecular weight E.coli Host Cell Proteins.  The product was purified from monospecific antiserum by Protein A affinity chromatography.
Formulation	0.02 M Potassium Phosphate, 0.15 M Sodium Chloride, pH 7.2
Concentration	1.38 mg/ml - lot specific
Conjugation	Unconjugated
Storage Condition	Store vial at -20° C or below prior to opening. This vial contains a relatively low volume of reagent (25 µL). To minimize loss of volume dilute 1:10 by adding 225 µL of the buffer stated above directly to the vial. Recap, mix thoroughly and briefly centrifuge to collect the volume at the bottom of the vial. Use this intermediate dilution when calculating final dilutions as recommended below. Store the vial at -20°C or below after dilution. Avoid cycles of freezing and thawing.
Background	Anti-HMW Host Cell Proteins Antibody recognizes high molecular weight protein fractions from E.coli. This antibody has been analyzed by 2D electrophoresis western blot to assure highest possible coverage of E.coli HCP. Host Cell Proteins are process-related impurities derived from a host cell expression system that may be present in trace amounts in a final drug substance. HCP Antibodies are used to detect impurities in biologically-based therapeutics. Detecting impurities often unseen by 1-D electrophoresis, a 2D electrophoresis western blot analysis delivers more complete insight into the immunocoverage of protein components of the host cell lysate.
Synonyms	rabbit anti-E.Coli Host Cell Protein antibody, rabbit anti-HCP antibody, rabbit Anti-Host Cell Protein, rabbit anti-HMW E.Coli HCP, rabbit anti-high molecular weight HCP
Note	Anti-HMW Host Cell Proteins Antibody detects over 250 E.coli HMW proteins and has been tested in 2D-Page, western blotting, and ELISA.
